Short answer

A print farm runs on filament that prints the same every time and fails as little as possible. PLA is the workhorse because it prints easy, runs fast, and costs the least per kilo, and a steady PLA line with tight tolerance does more for farm uptime than any exotic material. Buy on consistency and cost per kilo, then keep it dry.

Why the farm runs on PLA

A farm prints for margin, so the filament has to be cheap per kilo, fast, and forgiving. PLA hits all three. It prints easy at a low temperature, takes high cooling, and runs quick on most machines, so a farm of stock printers turns out parts with few fails. Per the Prusament PLA datasheet, PLA prints at a 210 C nozzle with a 10 C window and full fan, which keeps a farm line steady.

The cost is in the failures, not the spool. A cheap spool that drifts in diameter causes under-extrusion, and a failed overnight run costs more than a pricier, steadier line would have. Consistency beats the lowest price every time.

CriterionScoreNotes
Cost per kiloThe base cost. Buy by the kilo, not the spool, and standardize on 1.75 mm.
Batch consistencyA drifting batch fails runs. Reorder from a line that prints the same every time.
Low-fail rateThe real cost is failed prints. A steady line cuts overnight losses.
Print speedPLA runs fast, which raises farm throughput per machine.
StorageA farm holds a lot of open stock, so dry storage and desiccant matter.
Consistency and a low-fail rate beat the cheapest kilo.

Risks and what to check

The main risks on a farm are a batch that drifts, moisture in open stock, and a line that changes spec between orders. The defense: buy a sample lot and run it across the whole farm before a volume order, store opened spools dry, and keep a record of the lot number on each job so a bad batch is traceable.

Frequently asked

What is the best filament for a print farm?
PLA, in most cases. It prints easy, runs fast, and costs the least per kilo, and a steady PLA line with tight tolerance keeps farm fails low.
How do I cut failed prints on a farm?
Run a steady, tight-tolerance line, keep the stock dry, and log the lot number on each job. The cost is in the failures, not the spool, so consistency beats price.
Should a farm run more than one material?
Keep PLA as the bulk of the stock, and hold a smaller amount of PETG or ASA for the jobs that need toughness or heat. Standardize on 1.75 mm so any machine can run either.
